The short answer to the question “when should Saints fans freak out” is “not yet.” The slightly longer answer is “wait and see what happens in Detroit.” When Alvin Kamara isn’t on the field, the Saints’ offense looks anemic, and part of that is a seeming refusal from Drew Brees to throw the ball downfield.
Part of this, of course, is by design. The Saints’ offense is built in such a way that it accounts for Brees’ waning arm and instead relies on his pinpoint accuracy. However, as this season — in which the Saints have started 1-2 with two straight losses — wears on, defenses are going to continue to see that the Saints just aren’t going deep, and they’re going to adjust accordingly.
